The CLASS 20E trip curve means it allows a motor to draw up to 20 times its full-load current for about 20 seconds before tripping — standard for general-purpose induction motors driving pumps, fans, or conveyors where brief overloads during start-up are expected. The electronic overload release provides temperature-compensated protection across -25 to +60 °C, so ambient swings in a non-conditioned panel won't shift the trip point. The S2 size measures 55 mm wide by 81 mm tall by 109 mm deep. Stand-alone installation is the intended fastening method. It withstands shock up to 15 g for 11 ms per IEC 60068-2-27 (signaling contact derates to 8 g in tripped position) and vibration from 1 to 500 Hz. The substance prohibition date of October 15, 2014 indicates RoHS compliance for the EU market. No UL or CSA listing is stated in the available data.","metaTitle":"Siemens 3RB3036-2WX1 SIRIUS solid-state overload relay, S2,","metaDescription":"Siemens 3RB3036-2WX1 SIRIUS solid-state overload relay, S2 size, 80 A thermal current, CLASS 20E trip class.
