Feature Products
-
Rated current up to 6,300 A and higher for generator circuit breakers. Trip characteristics are often fully adjustable including configurable trip thresholds and delays. Usually electronically controlled, though some models are microprocessor controlled via an integral electronic trip unit. Often used for main power distribution in large industrial plant, where the breakers are arranged in draw-out enclosures for ease of maintenance.
-
An Automatic Transfer Switch (ATS) is often installed where a backup generator is located, so that the generator may provide temporary electrical power if the utility source fails.
-
In electrical power distribution, a busbar (also spelled bus bar, or sometimes as buss bar or bussbar) is a strip or bar of copper, brass or aluminium that conducts electricity within a switchboard, distribution board, substation, battery bank or other electrical apparatus. Its main purpose is to conduct a substantial current of electricity, not to function as a structural member.
-
Typically used in battery charger systems, DC audio systems, auxiliary and accessory circuits. Used in cars, trucks, buses, RVs and marine applications. 12VDC,20-300 Ampere thermal circuit breaker.
-
In electrical applications, a distribution box is a component that is used in a larger system that helps to regulate the flow of electricity through a distribution board. The concept behind the box is to provide for the orderly flow of current so that circuitry is not overloaded, leading to potentially dangerous situations.
-
Mainly used to indicate the status of a part of the installation, heater, motor, fan and pump etc.
-
MCB (Miniature Circuit Breaker)—rated current not more than 100 A. Trip characteristics normally not adjustable. Thermal or thermal-magnetic operation. There are three main types of MCBs: 1. Type B - trips between 3 and 5 times full load current; 2. Type C - trips between 5 and 10 times full load current; 3. Type D - trips between 10 and 20 times full load current.
-
Rated current up to 2,500 A. MCCB can be mounted in multi-tiers in low-voltage switchboards or switchgear cabinets.
-
Motor Protective device is suitable for starting motor in the circuit of AC 50/60Hz, voltage up to 660V and current up to 95A.
-
Residual current breaker with over-current protection (RCBO) — combines the functions of an RCD and an MCB in one package. In the United States and Canada, panel-mounted devices that combine ground (earth) fault detection and over-current protection are called Ground Fault Interrupter (GFI) breakers; a wall mounted outlet device or separately enclosed plug-in device providing ground fault detection and interruption only (no overload protection) is called a Ground Fault Circuit Interrupter (GFCI).
-
Residual current circuit breaker (RCCB) is an electrical wiring device that disconnects a circuit whenever it detects that the electric current is not balanced between the energized conductor and the return neutral conductor. Such an imbalance may indicate current leakage through the body of a person who is grounded and accidentally touching the energized part of the circuit. A lethal shock can result from these conditions. RCCBs are designed to disconnect quickly enough to prevent injury caused by such shocks.
-
The Shunt Trip (Release) Coil function is to allow mechanical tripping/opening of a Molded Case Circuit Breaker by a remote device other than by the overload & short-circuit mechanism already built into the breaker. (Usually thermally activated) In many cases the Shunt Trip function is used for Ground Fault protection of the equipment being supplied by the breaker however it can be used to trip/open the breaker for any reason. (Equipment Protection Interlock Permissives, Equipment Safety Permissives, Low Voltage & Over Voltage Protection, Buss Transfer Interlock, and many other reasons as dictated by the application needs.)
