ABB SN201 Series MCB, 40A Current Rating, 230V Rated AC Voltage - 2CSS255101R0404

This miniature circuit breaker (MCB) from ABB’s SN201 series is engineered to deliver reliable protection against overloads and short circuits in electrical systems. With a single-pole configuration and a 40A current rating, it is well-suited for circuits with higher load demands. Featuring a Type C tripping characteristic, it is Ideal for applications with moderate inrush currents, such as motor and fluorescent lighting circuits. Its Compact design, robust 10kA breaking capacity at 230V AC, and easy DIN rail mounting make it a dependable choice for both residential and commercial installations.

Features & Benefits

• Type C tripping characteristic for circuits with moderate inrush currents (e.g., motors, fluorescent lighting)
• Rated for 230V AC with a high breaking capacity of 10kA
• Single-pole design for Compact and efficient circuit protection
• Toggle switch actuator for simple and reliable reset operation
• DIN rail mounting for quick and secure installation in panels
• Compact dimensions (18mm width, 69mm length and depth) save valuable space in distribution boards
• Screw Terminal contacts ensure strong and secure wiring connections

Applications

• Suitable for residential, commercial, and light industrial electrical distribution systems
• Ideal for protecting circuits with higher load requirements such as motors, pumps, and lighting systems
• Commonly used in control panels, switchboards, and distribution boards
• Effective in environments requiring dependable overcurrent and short circuit protection

What does the Type C tripping characteristic mean?

Type C MCBs trip between 5 to 10 times the rated current, making them suitable for circuits with moderate inrush currents like motors and fluorescent lighting.

Can this MCB handle heavy-duty industrial loads?

While it is designed for moderate inrush currents, for heavy-duty industrial loads with very high surges, a Type D MCB may be more appropriate.

How is this MCB installed?

It is designed for DIN rail mounting, allowing quick, secure, and standardised installation in distribution boards and panels.
