All Spectra RMS circuit breakers from the SE150 through the SK1200, including instantaneous trip Mag-Break motor circuit protectors and molded case switches, use the same UL listed field-installable internal accessories that do not require cover removal to install. Shunt trip provides remote tripping of the breaker when used with a momentary close contact. Not recommended for use with a latching relay contact since electronics in the shunt trip will pulse power to the coil if continuously energized, and breaker shunt tripping upon reclosure will be delayed 1-2 seconds at rated control voltage. (A short circuit trip would be instantaneous.) If maintained (latching relay) contact must be used and delayed shunt tripping is not acceptable, use bell alarm in series with control power for SE150 and SF250 frames and auxiliary switch for SG600 and SK1200 breakers. These devices are suitable for use with ground fault sensing and relaying equipment. Maximum VA is 75. AC devices are UL listed for 50-60 Hz. SAST1849
