ABB High Performance S800N Miniature Circuit Breaker, 3-Pole, 63A, Type B, 690V ac AC, 375 V dc DC, 36 kA Breaking

This is a high performance MCB designed to deliver reliable electrical protection in commercial and industrial applications. The 3-pole construction accommodates a rated current of 63 A, making it suitable for a variety of installations. With dimensions of 81mm in width and 82.5mm in depth, this DIN Rail mount circuit breaker is engineered for maximum efficiency and safety.

• Supports voltages up to 690 V for versatile applications
• Includes thermal tripping for effective overload protection
• Electromechanical tripping guards against short circuits
• Fast arc extinction enhances operational safety

• Ideal for commercial electrical distribution boards
• Suitable for industrial machinery and equipment protection
• Used in residential where high performance is required
• Functions effectively in both AC and DC systems
• Supports diverse accessory integrations for custom needs

The circuit breaker employs two mechanisms, a thermal tripping mechanism for overload scenarios and an electromechanical tripping mechanism specifically designed for short circuit protection, ensuring comprehensive safety coverage.

Its fast arc extinction capability ensures that electrical arcs are quickly extinguished, significantly reducing the risk of electrical fires and damage to connected devices during fault conditions.

This circuit breaker has a maximum breaking capacity of 36 kA at 400 V, allowing it to effectively manage high fault currents and protect downstream circuits from damage.
