Meet the ABB SU201M-K1 — a reliable 1 A, 1-Pole circuit breaker engineered for dependable overcurrent protection in demanding electrical environments. Designed for panelboards, switchboards, and control panels, this compact breaker delivers precise protection where space is at a premium and safety matters most.

Key specifications at a glance

• Current rating: 1 A
• Poles: 1-Pole
• Breaker type: Circuit Breaker

The 1-Pole configuration offers flexible deployment across a range of distribution setups, making it a practical choice for both new installations and panel modernization projects. Whether you’re building a control cabinet for industrial equipment or expanding a switchboard, the SU201M-K1 provides the protection you need without unnecessary bulk.

Why this matters for your operation

• Targeted protection for low-current circuits: Designed to safeguard small-control and signaling circuits, sensors, and other low-load pathways within distribution panels and motor control centers.
• Consistent safety in demanding environments: The ABB 1A rating supports reliable interruption of fault currents, helping prevent damage to components and reducing downtime.
• Versatile deployment: With a 1-pole form factor, it fits neatly into panelboards, switchboards, and control cabinets, giving engineers a flexible protection solution without overcomplicating the layout.

Ideal for these applications

• Industrial facilities requiring protected control circuits and low-current protection within distribution panels
• Commercial electrical installations that call for compact, dependable overcurrent protection in panelboards
• OEM equipment where space and reliability are critical, particularly in motor control centers and auxiliary control panels

How it compares and ways to maximize value

Compared to higher-current breakers, the SU201M-K1 is purpose-built for low-current protection tasks. This specialization helps prevent nuisance tripping on sensitive control circuits while still delivering robust protection against overcurrent conditions. To get the most from this unit, pair it with compatible ABB panel hardware and ensure its 1-A rating aligns with the protected circuit’s load profile and anticipated fault scenarios.

Practical tips for use

• Verify that the protected load remains within the 1 A rating to avoid inadvertent trips during normal operation.
• Install in panels and control spaces where a compact 1-pole device can be accommodated without obstructing wiring channels.
• In motor control centers, use as the protective element for auxiliary circuits and low-load feeders to maintain overall system reliability.

For installers and engineers seeking dependable, low-current protection with straightforward deployment in panelboards, switchboards, and control panels, the ABB SU201M-K1 1A, 1-Pole circuit breaker delivers clear value—combining compact design with trusted ABB performance for industrial, commercial, and OEM environments.
