The Motor Circuit Breaker 7-10A is a three-pole motor protective circuit breaker from the 3RV10 range, designed for reliable switching, protection, and isolation of induction motors in industrial and electrical distribution applications. Also referred to as a motor protection switch or manual motor starter, this device is optimized for load feeders and provides compact, long-term stable motor protection in demanding environments. Built for short-circuit protection, motor protection, system protection, transformer protection, emergency stop switching, and fuse monitoring, the 3RV10 motor circuit breaker helps safeguard equipment while supporting dependable operation in control panels and automation systems. It is engineered with a rated operational voltage of up to 690V and short-circuit withstand capability up to 50kA at 400V AC, making it suitable for high-performance industrial use. This motor circuit breaker supports a maximum switching frequency of 15 operations per hour and offers a mechanical life of 10^5 operations, ensuring robust service life for repetitive switching duties. Its manual reset function adds convenience during fault recovery, while the lockable OFF position enhances operational safety during maintenance and service procedures. The 7-10A current rating makes it suitable for smaller motor loads requiring precise protection against overload and short circuits. With an ambient temperature range of -20 to +60 °C and long-term stability, it is suitable for diverse industrial installation environments when used with proper enclosure protection in dusty, damp, or vapour-prone conditions. Please note that this product is in obsolescence mode and is expected to be discontinued by the manufacturer. Buyers should review the manufacturer-recommended alternative or cross-reference options if long-term replacement planning is required. This unit carries approvals and compliance references including UL, CSA, IEC947, VDE0990, and EN60947, supporting use in regulated industrial applications.
