Why Choose the ABB SU202DC-Z1.6 Miniature Circuit Breaker?
The ABB SU202DC-Z1.6 is a high-performance 2-pole miniature circuit breaker (MCB) designed for dependable overload and short-circuit protection in DC electrical systems. As part of the specialised ABB SU200DC series, it combines a sensitive Type Z tripping characteristic with a 1.6 A rated current and high interrupting performance for demanding industrial, control and traction-related applications.
The SU200DC range is specifically designed for direct-current circuit protection and is available with K and Z tripping characteristics. Its thermal and magnetic protection mechanisms provide protection against sustained overloads and short-circuit faults, while the modular construction enables straightforward integration into electrical distribution and control panels.
With a 1.6 A rated current, 2-pole configuration, Type Z tripping characteristic and 14 kA interrupting rating, the SU202DC-Z1.6 is particularly suitable for sensitive circuits where rapid magnetic fault protection is required. The 2-pole SU200DC platform is designed for DC systems and provides simultaneous circuit interruption across both poles.

Reliable Protection for Sensitive DC Circuits
Miniature circuit breakers such as the ABB SU202DC-Z1.6 use thermal and electromagnetic tripping mechanisms to interrupt excessive current. The thermal mechanism responds to sustained overload conditions, while the electromagnetic mechanism provides rapid operation when a short-circuit fault produces a high current.
The Type Z characteristic is intended for circuits where sensitive protection against short-circuit currents is important. This makes the SU202DC-Z1.6 well suited to appropriate control, electronic and other low-current DC circuits where equipment may require a more sensitive magnetic response than higher-inrush applications.
Typical Applications
- DC electrical distribution systems.
- Industrial control and automation circuits.
- Low-current DC auxiliary circuits.
- Sensitive electronic and control equipment.
- DC control panels and distribution boards.
- Transport and traction-related DC electrical systems.
