ABB S201-K1.6 1.6A 1-Pole 277 V Circuit Breaker Potential Transformer

ABB S201-K1.6 1.6A 1-Pole 277 V Circuit Breaker Potential Transformer is a compact, dependable protection device designed for 277-volt electrical networks. With a single-pole construction and a precise 1.6 A current rating, this breaker is tailored for low-load control circuits, instrumentation lines, and small-professional installations where accurate protection matters most.

Key advantages at a glance:

• Current rating: 1.6 A—provides targeted protection for sensitive control circuits, lighting control networks, and small equipment without triggering unnecessary trips.
• Voltage rating: 277 V—suitable for commercial and light industrial distribution that commonly operates at 277 VAC, aligning with modern building systems.
• 1-pole design—maximizes panel space and simplifies wiring in centralized control panels and compact electrical enclosures.
• ABB reliability—part of ABB’s trusted S201 family, built to endure routine operation in demanding environments and support long service life.
• Easy maintenance and replacement—clear labeling and standardized form factor help technicians identify and swap components quickly during routine servicing.

This breaker is ideal for forming a reliable protective layer in control panels, lighting distribution networks, HVAC control circuits, and instrumentation runs where low current protection is essential. Unlike higher-current devices, the S201-K1.6 protects these circuits from overloads without compromising system performance, helping to prevent nuisance outages and equipment damage.

Practical scenarios where it shines include retrofitting older panels with modern, low-current protection, stocking spares for ABB installations, and configuring new 277 V control networks in commercial buildings. Its compact footprint and single-pole configuration make it a pragmatic choice for spaces where every ampere and every inch of panel space counts.

If you’re organizing a parts kit for ABB-compatible equipment or designing a small, reliable 277 V protection solution, the ABB S201-K1.6 1.6A 1-Pole 277 V Circuit Breaker provides precise current protection, straightforward installation, and dependable performance you can trust in everyday electrical environments.
