Technical Specifications

Contact configuration: 1P + N (single pole with neutral wire), the live wire pole has overload and short circuit tripping functions, while the neutral wire pole only isolates without disconnecting, ensuring absolute safety during maintenance.

Rated voltage: AC 230/400V, covering mainstream industrial low-voltage power grid standards, with an insulation voltage of 690V.

Rated current: 1.6A. Specifically designed for micro-sized motors, the overload protection setting range covers 1.2A - 1.6A, with extremely sensitive response.

Mechanical life: Up to 100,000 operation cycles.

Application scope

PLC and control system power distribution: As the secondary side protection of control transformers or the precise power distribution switch for PLC I/O ports, it provides reliable short-circuit rapid protection. High-density MCC cabinets: With a ultra-thin body of only 45mm width, it enables more circuits to be accommodated in cramped motor control centers (MCCs), significantly reducing the cost of cabinet renovation. Frequent operation of heavy equipment: With a high interrupting capacity of 10kA, it can still extinguish arcs in short-circuit conditions near the transformer, protecting expensive equipment at the rear from being burned.

After-sales service

The warranty commitment offers a 12-month global warranty starting from the time of factory delivery. For cases such as tripping failure or shell rupture caused by material or craftsmanship issues, free replacement is provided. Rapid emergency response: Authorized stock channels guarantee in-stock delivery within 24 hours. In case of emergency shutdown of the production line, they provide emergency replacement with the same specification spare parts. Technical diagnosis and selection replacement: The professional after-sales team offers answers to wiring terminal diagrams and matching diagnosis of tripping curves; if the model is discontinued, an upgrade alternative solution is provided.

FAQ Module

Q1: When used in a dusty workshop, how are the dust-proof and protection levels of this model ensured?

A1:The body of 3RV6021-4AA15 is protected by IP20 standard, which can only prevent accidental touch. If it is installed in a dusty environment, it is strongly recommended to add a SIRIUS 3RV6911 series sealing cover. With this addition, the front protection can be fully enhanced to IP65, effectively blocking conductive dust and preventing poor contact between the contacts, thus avoiding incorrect actions caused by poor contact.

Q2: How can one quickly distinguish whether a circuit breaker trips due to "overload" or "short circuit"?

A2: Observe the position of the handle and the tripping indicator. During an overload trip, the handle usually remains in the middle position, and the front of the circuit breaker will pop out the tripping indicator plate (a red mark); during a short circuit instantaneous trip, the handle is also in the middle position, but the action is extremely fast and often accompanied by an internal arc breakdown sound. Use a multimeter to check the insulation between phases/ground.
