Short-circuit Withstand Current

Molded case switches are identical to molded case circuit breakers, except they are not equipped with trip units and sensors. Molded case switches open when the handle is switched to the OFF position or in response to an auxiliary tripping device such as a shunt trip or an undervoltage release.

These switches open instantaneously at a non-adjustable, factory preset, magnetic trip point calibrated to protect only the molded case switch itself. Magnetic settings:

•NSF150/250 A switches: 2000 A

•NSJ 400/600 A switches: 6000 A

These switches are suitable for use on a circuit capable of delivering not more than:

•240 V: 100 kA for NSF switches and 150 kA for NSJ switches

•480 V: 65 kA for NSF switches and 100 kA for NSJ switches

•600 V (600Y/347 for NSF switches): 25 kA

Switches are Listed under UL file E103740 and Certified under CSA file LR 88980.
