This three‑pole device provides Class 10 thermal‑magnetic protection with an A‑REL release and is rated for continuous currents up to 16 A, with adjustable trip settings from 11 to 16 A to tailor protection to motor load and startup profiles. It is rated for up to 690 V AC operation (typical motor circuits span 220–690 VAC) and offers a short‑circuit breaking capacity of 208 A, making it suitable for safeguarding motors against overloads and faults in industrial panels. Terminals are screw type, and an auxiliary switch option is available for signaling or control interlocks. The enclosure front is IP20, it supports an impulse voltage resistance of 6 kV, and its mechanical life is specified at about 100,000 switching cycles, delivering durable performance in everyday factory use. In practical terms, this protector pairs with motors up to roughly 7.5 kW at 220–690 VAC and is designed for DIN rail mounting, streamlining integration into compact motor control architectures.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268129181930,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-3rv1021-4aa10-motor-protection-switch","provider":"GTG Hardware","version":"1.0","type":"link"}
