Overcurrent circuit breaker, 4P, C characteristic, 63A, 10kA, AC | S204M-C63 2CDS274001R0634

Electrical installation protection with S204M-C63 circuit breaker

This four-pole circuit breaker with C characteristic is a reliable protection for your electrical installation. Designed by ABB, the S204M-C63 model combines compact dimensions and high protection efficiency against overloads and short circuits. It is a key element in ensuring safety and power continuity in residential, commercial and industrial buildings.

This circuit breaker, belonging to the S200M series, is distinguished by its versatility and compliance with applicable standards (EN 60898-1 and EN 60947-2). This guarantees that it meets the requirements for safety and quality. Its rated current of 63A and short-circuit breaking capacity of up to 10kA (at 230V) guarantee effective protection even in demanding conditions.

Characteristics and application

The C characteristic means a delayed thermal release time. This makes the circuit breaker cope well with impulse loads, such as starting electric motors or transformers – without unnecessarily disconnecting the circuit. At the same time, fast electromagnetic tripping reacts immediately to sudden current surges caused by a short circuit, minimizing the risk of damage to the installation and equipment.

The S204M-C63 circuit breaker is ideal for protecting lighting circuits, socket outlets and other receivers with moderate starting current. Its wide operating temperature range (-25°C to +55°C) allows installation in various environmental conditions. Mounting is done on a DIN rail, which facilitates and speeds up installation.

Key features and benefits
