Altech has the circuit breaker you need!

Altech circuit breakers are DIN rail mounted and meet UL489, UL508 or UL1077 approvals with a short circuit interrupt capacity up to 10kA! This is just one of the many advantages Altech can off you with their industrial circuit breakers.

Altech UL508 circuit breakers offer overload protection, switching function and disconnect function (when suitable). Take a look now at the new modern look and color on our most popular series.

When you need branch circuit protection Altech offers UL489 miniature molded case circuit breakers in both AC and DC voltages. 

The Altech UL489 circuit breakers offer overload & short circuit protection, switching function and disconnect function.

If your application requires supplemental protection for control circuits and on the load side of branch circuit protectors we offer our Altech UL1077 supplementary protectors! These circuit breakers offer overload protection.

Marshall Wolf Automation is your industrial automation distributor for the full line of Altech circuit breakers. We also offer a complete offering of UL508 and UL489 busbar systems and large UL489 molded case circuit breakers.

We've all seen them or, let's face it, had to track them down to restore power to something in our house!

What exactly is it that circuit breakers do?

 

• UL1077 circuit breakers 
• UL489 circuit breakers
• UL508 circuit breakers
• Molded case circuit breakers (MCCB)
• AC and DC circuit breakers

Here are the basics on these two popular types of miniature circuit breakers; UL489 and UL1077.

UL489 Circuit Breakers (Branch Protection)

• Branch circuit protection in control panels, motor control centers and panel boards
• Motor overload and motor short circuit protection for control panels and motor control centers
• Stand-alone branch circuit protection

UL1077 Circuit Breakers (Supplementary Protection)

• Not suitable for the protection of branch circuit conductors - supplemental protectors do not have standard overload characteristic performance levels and cannot assure proper protection of branch circuits.
• For use where branch circuit protection is already provided or is not required
• Generally used with control circuits, control power transformers, relays, PLC I/O, lighting circuits, appliances
• Over-current or over-/under- voltage protection
• Excellent fuse replacement when fuses are applied as supplementary protection

If you are still unsure of which type of circuit breaker your application requires feel free to contact our in-house technical department for assistance.

Marshall Wolf Automation is your authorized industrial automation distributor for a wide range of circuit breakers including Altech circuit breakers, Chint, IDEC and Weg.

Today's 'My Automation Education' is going to focus on a little piece of knowledge I learned this week while Altech was in our office. We're going to talk about circuit protection; the very basic beginnings of it. Why is circuit protection necessary? There are not tiny raiders coming to pillage your circuits while you are sleeping. Instead, the basic goal of circuit protection is to detect a fault condition and immediately cut electrical flow. Examples of these fault conditions would be overloads and short circuits. There are two basic types of circuit protection: fuses and circuit breakers. According to wikipedia: Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city. Today we will focus on circuit breakers.

One very popular line sold at Marshall Wolf Automation is from Altech. They offer three solutions to myriad circuit protection needs. Lets break down their offerings:

UR Series - UL1077 Recognized Supplementary Protectors

This line provides only overload protection. They are available in both 277V AC and 480Y/277 V AC voltage ratings. They come in 1, 2, or 3 pole and offer 0.5-60 amps in B, C, and D trip curves.

V-EA Series - UL508 Listed Manual Motor Controllers

This line provides overload protection, as well as switching and disconnect functions. This allows you to use them as a motor disconnect so you can safely work on a single segment of your line without having to shut off your entire main breaker. They are available in 277V AC, 480Y/277 V AC, 42V DC, 80V DC, 24V DC, and 60V DC voltage ratings. They are offered in a variety of amperages from 0.3-60amps (1, 2, or 3 pole depending on voltage rating) and come in 6 (B, C, D, E, G, and Z) trip curves. They are an excellent option for applications where UL1077 is not enough and UL489 is just over kill.

UL (AC), DL (DC) Series - UL489 Miniature Molded Case Circuit Breakers

This line offers the overload protection, switching and disconnect functions, of the UL508 but also adds short circuit protection. They are available in 240V AC, 277V AC and 480Y/277V AC voltage ratings in ranges of 0.3-63 amps in 1, 2, or 3 poles for 4 (B, C, D, and Z) trip curves.

The potential down time from unprotected circuits is not worth the relatively low cost of installing them. Call and speak with our technical department to find the correct fit for your application, or check out our website to see for yourself. Marshall Wolf Automation should be the #1 choice as your industrial automation distributor.

What do earth leakage circuit breakers do? Earth leakage circuit breakers, also called ELCB's and residual current circuit breakers, detect and interrupt earth (ground) faults.

The main purpose when using earth leakage circuit breakers (ELCB's) is to prevent injury to humans and animals due to electric shock.

Altech's FI series of earth leakage circuit breakers are also VDE approved for the European market!

Applications include ground fault protection of equipment (GFPE) and fire prevention by limiting the energy of a fault to less than the minimum ignition energy for many materials.
