AutomationDirect Supplementary Protector Breakers (For protection against shorts and overloads)
Supplementary Protectors (Circuit Breakers)AutomationDirect is pleased to offer Cutler-Hammer™ WMS Series Supplementary Protector Breakers by Eaton Corporation. These are standard supplementary protector breakers, recognized by UL and CSA under UL 1077 and CSA 22.2. They are CE marked in accordance with Low Voltage Directive (LVD) (73/23/EEC). They are thermal magnetic and protect against short circuit and overload conditions. These DIN-rail mounted supplementary protectors come in one, two and three pole configurations and now are available in three trip curves. The new C curve protector magnetic trip point is 5 to 10 times the rated current and is typically used for control circuits. The existing B curve protector magnetic trip point is 3 to 5 times the rated current and The D curve magnetic trip point is 10 to 20 times the rated current. Supplementary Protector prices start at $8.50.These supplementary protectors are used to provide overcurrent protection where branch protection (for example, UL 489 MCCB) is already provided or not required. The units can be installed as a component within or part of an appliance or a piece of electrical equipment. They are ideal replacements for fuses that are applied as a supplementary protector, i.e. in addition to branch protection (if required). They are 35 mm DIN-rail mountable, utilizing a metallic “extra strength” spring clip.Single-Pole supplementary protectors are priced at $8.50 Double-Pole supplementary protectors are priced at $17.00 Triple-Pole supplementary protectors are priced at $24.00Applications These supplementary protectors are to be applied in conjunction with a branch protector (if branch protection is required) and can be a replacement for similarly applied fuses. The advantage over fuses is that these devices are resettable and the status is easily and clearly identified by the position of the handle and the flag indicator. These supplementary protectors provide a wide range of current ratings from 0.5 to 60 amperes and three different overcurrent characteristic curves: B, C and D. You can select a device that provides maximum reliability and accuracy to fit various applications.With 35 mm DIN-rail mounting and “Quick 3 Step” field mountable accessories, it is easy for you to select and apply these supplementary protectors. Cutler-Hammer WMS Series Supplementary Protector Breakers are ideal for providing protection in a multitude of applications, including:
Control power transformers
Relays
Contactor coils
Lighting circuits Features, Benefits, and Functions
Current limiting design provides fast short circuit interruption that reduces the let-through energy which can damage the circuit.
Thermal Magnetic Overcurrent Protection: Two levels, categorized by B, C and D curves. In direct relation to continuous rating of the device. - B Curve Trip - 3 to 5 X rated current Suited for applications where maxmum protection is required for control circuits from low level short circuit faults that could damage the wiring. - C Curve Trip - 5 to 10 X rated current ... New! Typically used for control circuits. - D curve Trip - 10 to 20 X rated currentProvides a magnetic range to allow for higher inrush levels during startup, that are usually seen with transformers and other high inductive systems.
Color coded status indicator window: Red = ON or Green = OFF.
