AutomationDirect: Gladiator Miniature Circuit Breakers (GMCBU Series)
November 10, 2020
Gladiator miniature circuit breakers offer optimum and efficient protection for branch and control circuits up to 63 amps. The Gladiator series is available with B, C or D trip characteristics in accordance with UL 489. The Gladiator series units are DIN rail mountable and can be used in feeder and branch circuit applications.
Applications
Feeder and Branch Circuit Protection
- – PLC I/O points
- – Motor control circuits
- – Control instrumentation
- – Power supplies
- – Relays
- – Convenience receptacle circuits (internal / external)
- – Load circuits leaving the equipment (external)
- – Computers
- – UPS
- – HACR Equipment (Heating Air Conditioning, Refrigeration)
- – Power conditioners
- – Dual rated for AC or DC applications
- – Complete range of UL 489 listed DIN rail mounted miniature circuit breakers up to 63 amp current rating
- – Single-pole, two-pole and three-pole models
- – Suitable for reverse feed applications
- – Suitable for branch circuit device protection
- – Trip-free design – breaker cannot be defeated by holding the handle in the “ON” position
- – Captive screws cannot be lost
- – Can also be used in applications for which UL 1077 or CSA C22.2 No.235 are also allowed
- – Field installable shunt trip and auxiliary switches, side mountable
- – Module width of only 18mm [0.71 in] (per pole)
- – Contact position indicator (red / green)
- – 35mm DIN rail mountable, utilizing spring clip
Thermal magnetic overcurrent protection:
- – Three levels of short circuit protection, categorized by B, C and D curves
- – B-curve magnetic trip point: 3 to 5 times the rated current, typically used for esistive loads such as conductors or heaters.
- – C-curve magnetic trip point: 5 to 10 times the rated current, typically used for small transformers, pilot devices, etc.
- – D-curve magnetic trip point: 10 to 20 times the rated current, typically used for transformers or very high inductive loads.
