2CDS271334R0448 ABB ST201M-Z13 13A 1P Z Curve 15kA Miniature Circuit Breaker

Why Choose the ABB ST201M-Z13 Miniature Circuit Breaker?

The ABB ST201M-Z13 is a high-performance single-pole miniature circuit breaker (MCB) / supplementary protector designed to provide reliable overload and short-circuit protection in industrial control, automation and equipment circuits. With ABB order code 2CDS271334R0448, it forms part of the ABB ST 200 M series of modular DIN-rail circuit protection devices.

Designed for applications requiring sensitive overcurrent protection, the ST201M-Z13 combines thermal and magnetic tripping to protect conductors and connected equipment against overload and short-circuit conditions. Its Z tripping characteristic provides a sensitive magnetic response, making it particularly suitable for control, electronic and other equipment circuits where rapid response to overcurrent is required.

Rated at 13 A, the ST201M-Z13 provides an IEC rated ultimate short-circuit breaking capacity of 15 kA at 230 V AC. It is also classified as a UL 1077 supplementary protector, with a UL 1077 interrupting rating of 10 kA at 240 V AC, 277 V AC and 60 V DC, providing versatile supplementary protection for industrial equipment.

Sensitive Circuit Protection for Industrial Systems

Miniature circuit breakers such as the ABB ST201M-Z13 provide automatic protection against overload and short-circuit conditions. The thermal element responds to sustained overloads, while the magnetic element provides rapid operation during sufficiently high fault currents, helping protect conductors and connected electrical equipment from damaging overcurrent conditions.

The ST201M-Z13's 13 A rating and Z tripping characteristic make it particularly useful for sensitive control and equipment circuits requiring a comparatively fast magnetic response. Its combination of IEC performance and UL 1077 supplementary protection makes it suitable for integration into a wide range of industrial machinery, automation and electrical equipment designs.

Typical Applications

• Industrial control panels and automation systems.
• Machine control and auxiliary circuits.
• Sensitive electronic and electrical equipment.
• Control, signalling and instrumentation circuits.
• Supplementary protection within industrial electrical equipment.
• DIN-rail control and electrical distribution assemblies.
