Bussmann 170H0047 UL 489 Supplementary Protector Circuit Breaker, 13A Two-Pole

Bussmann 170H0047 UL 489 Supplementary Protector Circuit Breaker, 13A Two-Pole

The Bussmann 170H0047 is a UL 489 industrial miniature circuit breaker configured as a supplementary protector, rated 13A with a 5-10X trip characteristic. Built as a two-pole device with standard terminals, this breaker delivers dependable overcurrent protection for industrial control and equipment circuits. Its compact two-pole configuration and standard terminal design make it well suited for integration into panels and equipment where reliable, code-referenced circuit protection is required. As a supplementary protector, the 170H0047 adds a defined, factory-set layer of overcurrent protection within equipment or control assemblies that are already protected upstream by a branch-circuit device, giving panel builders and OEMs a compact two-pole device sized specifically to the 13A load it serves.

Key Features

• Amperage Rating: Rated 13A, the 170H0047 provides supplementary overcurrent protection sized to the connected circuit load.
• Two-Pole Configuration: Two-pole construction allows a single device to protect two-conductor circuits.
• 5-10X Trip Characteristic: The 5-10X /n trip rating defines the instantaneous magnetic trip multiplier, providing predictable response to overload and short-circuit conditions.
• Standard Terminals: Standard terminal connections simplify field wiring and termination in panels and equipment.
• Industrial Standard: Constructed to the UL 489 industrial miniature circuit breaker standard for supplementary protector applications.
