It carries a 187 kA interrupting capacity at 240 V and 121 kA at 415/440 V, with a rated insulation voltage of 800 V. The 40 A continuous rating holds across the full ambient range from 40 °C to 70 °C — no derating needed in a warm enclosure. The interrupting capacity of 187 kA at 240 V and 121 kA at 415 V means this breaker can clear high-fault currents typical in industrial main feeders without cascading upstream. The 800 V insulation voltage supports 480/600 V class systems with margin. The ETU550 trip unit allows field adjustment of the long-time, short-time, instantaneous, and ground-fault pickup levels, so you can coordinate selectivity with downstream breakers. The breaker measures 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures. The communication function supports integration with energy management or SCADA systems via the SENTRON bus.","metaTitle":"Siemens 3VA2040-5JP36-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU55","metaDescription":"Siemens SENTRON 3VA2040-5JP36-0AA0 molded case circuit breaker, 40 A rated, 3-pole, ETU550 trip unit. 187 kA at 240 V.
