Product Feature

- These circuit breakers are intended for the protection of circuits against overloads and short circuits in residential, commercial and industrial premises;

- It covers the rating range from 6 to 63A with a uniform breaking capacity of 6.5 kA throughout;

- Current-limiting scheme: in the event of a short circuit, are able to limit the let-through current to 60%-70%  of the rated current;

- The arc extinguishing system: allows the short-circuit currents of very high value to be interrupted extremely rapidly, the remarkable opening speed of contacts opening and the structure of the arcing chamber contribute to extinguishing the arc in the shortest possible time;

-The sensitivity and reliability of the trip mechanism ensures perfect closure every time,thereby considerably improving the performance of these devices and extending their average lifetime;

- The internal contact position allows an exact information of the circuit-breaker status:“green”, open contacts;“red”, closed contacts,independently of the toggle position;

- Sealing/locking sealable with 1 mm wire , to prevent unwanted  tripping;

- The supply lines of the protected circuit can be connected to either the upper or lower terminals of the circuit-breakers(reversibility of connections). The double terminal of these circuit-breakers enables simultaneous connection of cables and busbars.

Reconditioned Circuit Breakers

The EHC3100 Circuit Breaker has been reconditioned per MIDWEST’s rigorous service procedures based on 30 years experience. The EHC3100 circuit breaker has been maintained and refurbished per industry standards and per MIDWEST’s Quality Control Program (QCP). The services include applicable internal and external procedures, repairs, and replacement of deficient components. In addition to standard electrical tests, MIDWEST also performs live function tests on the EHC3100. These services far exceed the routine reconditioning of the EHC3100 performed by many circuit breaker vendors and resellers. MIDWEST certifies the EHC3100 circuit breaker has passed our QCP before shipping.

New Surplus Circuit Breakers

A “New Surplus” Circuit Breaker is a circuit breaker that has never been installed, but is not “New from the Factory” or “New from the Manufacturer or Distributor” of the EHC3100 circuit breaker. It may be referred to as New in the Box, New Surplus, Never Installed, Never Energized, or other such term that avoids the label “New from the Manufacturer.” A New Surplus EHC3100 circuit breaker should not be considered new from the manufacturer or manufacturer’s Distributor. Surplus and New Surplus EHC3100 circuit breakers must pass MIDWEST’s (QCP) Quality Control Program.
