High Density UL489 Circuit Breakers:
13mm Wide per Pole

ASI UL 489 circuit breakers are 25% thinner compared to standard sized din rail circuit breakers.  This compact size adds value to the system integrator who has space constraints. These industrial circuit breakers provide branch circuit protection for 120 Vac and 240 Vac applications, interrupt capacity of 10kA for 1 pole and 5kA for the 2 and 3 pole versions. The lowest current rating is with the single pole at 0.5 Amp 25 Amps. All three configurations offer up to 25 Amp current ratings.

Features:
  • UL489 Listed for Branch Circuit Protection
  • Rated from .1 to 25 amps
  • Compact width, 13mm / pole
  • Shock Proof Connections
  • Standard 35mm DIN Rail Mounting
  • Busbar and Lockout/Tagout Accessories Available.
