Product Description

The Siemens SENTRON 5SL4463-7RC-Z12 is a high-performance 63A 4-pole Miniature Circuit Breaker (MCB) designed to provide reliable protection against overload and short-circuit conditions in AC electrical installations. With a C-type tripping characteristic, 10kA breaking capacity and 415V AC rated voltage, this Siemens MCB is suitable for industrial, commercial and electrical distribution applications.

The 5SL4 series MCB is engineered for dependable circuit protection in distribution boards, control panels and low-voltage electrical systems. Its 4-pole configuration allows simultaneous protection and switching of a three-phase electrical circuit with neutral, making it suitable for three-phase distribution systems and industrial electrical panels. Siemens specifies the standard 5SL4463-7 model as a 4-pole, C-characteristic, 63A miniature circuit breaker with a 10kA rated short-circuit capacity.

The C Curve MCB is suitable for circuits where moderate inrush currents may occur, such as motors, transformers, lighting systems and other electrical loads. The 10kA short-circuit breaking capacity provides a high level of fault-current interruption capability for suitable low-voltage installations.

With its compact modular construction and DIN-rail mounting design, the Siemens 5SL4463-7RC-Z12 63A MCB can be easily integrated into electrical distribution boards, industrial control panels, commercial buildings, machinery and automation systems. The 5SL4 range is part of Siemens SENTRON miniature circuit breakers and is an active product family.
