Circuit Protection

Product Description
Eaton's WMZ 35 mm DIN-rail mountable circuit breaker is designed for use in branch service applications. The WMZ is available with C and D characteristics in accordance with UL 489, and CSA 22.2 No. 5 and IEC 60947-2. WMZ circuit breakers are provided in ranges from 0.5 to 40 amperes continuous in one, two, and three-pole configurations. This breaker provides thermal-magentic overcurrent protection of branch circuits.

Features, Benefits and Functions

• Complete range of UL 489 listed DIN-rail mounted miniature circuit breakers up to 40 amperes current rating.
• Standard ratings of 10 kAIC at 277/480 Vac
• Select amperages available at 14 kAIC at 277/480 Vac and 10 kAIC at 125 Vdc
• Current-limiting design provides fast short-circuit interruption that reduces the let-through energy, which can damage the circuit.
• Suitable for branch circuit device protection
• Thermal-magnetic overcurrent protection
  - Two levels of short-circuit protection, categorized by C and D curves
• Trip-free design - breaker can not be defeated by holding the handle in the ON position
• Captive screws can not be lost
• SWD (switching duty) - suitable for switching fluorescent lighting loads (l ≤ 20A)
• Fulfill UL 489, CSA 22.2 No.5 and also IEC 60947-2 Standard
• For use in applications for which UL 1077 or CSA C22.2 No.235 are also allowed
• Field installable shunt trip and auxiliary switch subsequent mounting
• Separate version for ring-tongued connection (Type WMZT....T), terminal screws can be removed (on both sides)
• Module width of only 1.7 mm (per pole)
• Contact position indicator (red/green)
• Easy installation on DIN rail
• Possibility for sealing the toggle in ON or OFF position
