At 45 mm wide, it fits a standard modular panel slot. The 10 A continuous rating sets the motor FLA it can protect. Breaking capacity is 100 kA at 400 V AC and 240 V AC, 42 kA at 500 V AC, and 6 kA at 690 V AC. At 400 V, that 100 kA SCCR means it clears a bolted fault without the arc flash escalating — critical for panel coordination studies. The 4 kW motor rating at 400 V lines up with a typical 10 A motor full-load current on a 400 V line. IP20 on the front means fingers won't reach live parts inside the panel. The -50 to +80 °C storage range and -20 to +60 °C operating range cover unheated warehouses and hot machine cabinets. Shock rated at 25g / 11 ms — it stays calibrated on a vibrating conveyor or pump skid. Zero clearance needed at the sides or back — 0 mm backwards and 0 mm at the side — so you can pack it tight in a crowded panel. Dimensions: 45 mm wide, 97 mm tall, 96 mm deep. Screw terminals accept 1x to 2x (1... 2.5 mm²) solid or stranded, and 2x (2.5... 6 mm²) solid or stranded on the main circuit. Fine-stranded with ferrule: same ranges. AWG equivalents: 2x (14... 10). Auxiliary and control circuits also use screw terminals. An auxiliary switch can be added — the product extension for that is supported. RoHS compliant per the substance prohibition date of 01.05.2012. The rated impulse withstand voltage is 6 000 V, and operating frequency for AC-3 duty is max 15 operations per hour.","metaTitle":"Siemens 3RV1021-1JA10-ZW95 SIRIUS Motor Protective Circuit B","metaDescription":"Siemens SIRIUS 3RV1021-1JA10-ZW95 motor-protective circuit breaker, 10 A continuous, Trip Class 10, 100 kA breaking at 400 V AC.
