Automatic Molded Case Switch Specifications

Automatic Switch Functions

An automatic switch can be used to open and close a circuit breaker under normal operating conditions. They are similar in construction to circuit breakers, except that the switches open instantaneously at a factory-set, non-adjustable trip point calibrated to protect only the molded case switch.

Molded case switches are intended for use as a disconnect device only. UL489 requires molded case switches to be protected by a circuit breaker or fuse of equivalent rating. Molded case switches are labeled with their appropriate withstand ratings. The withstand rating of a switch is defined as the maximum current at rated voltage that the molded case switch will withstand without damage when protected by a circuit breaker with an equal continuous current rating.

PowerPact B-frame automatic switches are available in unit mount versions. They use the same accessories and offer the same connection possibilities as the circuit breaker versions.

Switches are Listed under UL file E103740 and Certified under CSA file LR88980.

Automatic Switch Protection

The automatic switch can make and break its rated current. For an overload or a short circuit, it must be protected by an upstream device, in compliance with installation standards. Due to their high-set instantaneous release, PowerPact B-frame automatic switches are self-protected.
