Overcurrent circuit breaker, 1P, D characteristic, 63A, 6kA, AC | S201-D63 2CDS251001R0631

Protection of installations and devices – overcurrent circuit breaker series S201

This single-pole overcurrent circuit breaker from ABB with D characteristic is a reliable protection for electrical installations. Designed to protect against overloads and short circuits, it ensures safe operation of electrical devices in residential, commercial and industrial buildings. Rated current of 63A and breaking capacity of 6kA (at 230/400V AC) guarantee effective protection even in demanding conditions.

Characteristics and application

The S201-D63 circuit breaker with D characteristic is particularly recommended for protecting circuits with receivers with high inrush current, such as motors, transformers or heating devices. The D characteristic allows for short-term exceeding of the rated current without unnecessary tripping, which prevents false alarms and downtime of devices. Mounting on a TH-35 rail facilitates installation and integration with an existing switchgear.

• Application: circuits with high inrush current (motors, transformers, heaters), installations in residential, commercial and industrial buildings.
• D characteristic: delayed reaction to short-term current surges – ideal for motor-driven devices.
• Breaking capacity: high resistance to short-circuit currents – 6kA at 230V AC and 400V AC.
• Mounting: quick and easy mounting in the switchgear – on a TH-35 rail.
• Wire cross-section: possibility of connecting solid wires with a cross-section from 0.75 to 35 mm² and stranded wires from 0.75 to 25 mm².

Technical parameters and construction

The circuit breaker is characterized by a compact design (width 1 module) and a high degree of protection IP20, which ensures safety of use in various environmental conditions. Made of high-quality materials, it guarantees long-lasting and reliable operation. The rated insulation voltage Ui is 440V, and the rated impulse withstand voltage Uimp is 4kV. The energy limitation class is 3, and the surge category is III, which confirms its compliance with applicable safety standards. Power losses are 4.8W at rated voltage 230V and frequency 50/60Hz.
