2CDS271334R0101 ABB ST201M-D10 10A 1P D Curve Miniature Circuit Breaker

Why Choose the ABB ST201M-D10 Miniature Circuit Breaker?

The ABB ST201M-D10 is a high-performance single-pole miniature circuit breaker (MCB) / supplementary protector designed to provide reliable overload and short-circuit protection in industrial and commercial electrical systems. With ABB order code 2CDS271334R0101, it forms part of the ABB ST 200 M series of modular DIN-rail circuit protection devices.

Designed for demanding applications requiring dependable circuit protection, the ST201M-D10 combines thermal and magnetic tripping in a compact modular format. Its D tripping characteristic makes it particularly suitable for circuits supplying equipment with relatively high starting or inrush currents, while its trip-free switching mechanism provides dependable operation under fault conditions.

The ST201M-D10 has a rated current of 10 A, a single-pole configuration and an IEC rated ultimate short-circuit breaking capacity of 15 kA at 230 V AC. For UL 1077 applications, it provides a 10 kA interrupting rating at 240 V AC, 277 V AC and 60 V DC, making it a versatile supplementary protector for industrial control equipment and machinery.

Reliable Circuit Protection for Industrial Systems

Miniature circuit breakers such as the ABB ST201M-D10 provide automatic protection against overload and short-circuit conditions. When current exceeds the permitted operating range, the circuit breaker's thermal-magnetic tripping mechanism disconnects the protected circuit, helping prevent damaging overcurrent from reaching connected wiring and electrical equipment.

The ST 200 M series is designed for demanding industrial applications where compact modular protection and dependable switching performance are required. The ST201M-D10's 10 A rating and D tripping characteristic make it particularly suitable for circuits supplying loads with relatively high inrush currents, while its UL 1077 classification supports use as a supplementary protector within electrical equipment.

Typical Applications

• Industrial control panels and automation systems.
• Machine control and auxiliary circuits.
• Circuits supplying loads with high starting or inrush currents.
• Transformers and inductive loads where a D-curve characteristic is appropriate.
• Supplementary protection within electrical equipment.
• Commercial and industrial electrical distribution assemblies.
