Circuit breaker testing includes electrical test, mechanical test, temperature rise test, and insulation test. Testing of circuit breakers requires highly equipped laboratories and sophisticated testing procedures. Standard specifications give and describe in detail the tests to be carried out on circuit breakers and how they are performed.

Circuit breaker is a device for closing and interrupting a circuit between separable contacts under both normal and abnormal conditions. It is arbitrarily grouped using many different criteria such as the intended voltage application, the location where they are installed, their external design characteristics, and, perhaps most importantly, by the method and the medium used for the interruption of current. It is required to control electrical power networks by switching circuits on, by carrying load and by switching circuits off under manual or automatic supervision. It is also designed to open a circuit automatically on a predetermined overload or ground-fault current without damage to itself or its associated equipment.

Circuit Calibrators system are used in both in public buildings and industrial plants. A unique feature or the track circuit calibrator is that its resistance elements are enclosed in the shunt cartridge, protected from tool box wear and tear. Explosion-proof measuring and calibrating equipment are multi function calibrator, circuit calibrator, universal temperature calibrator, and pressure calibrators.

Circulation Heaters provides ready made means to install electric heating with a minimal amount of time and labor. This is accomplished by combining heating elements, vessels, insulation, terminal enclosure, mounting brackets, and inlet and outlet connections into a complete assembly. It is made from NPT screw plug or ANSI flange heater assemblies mated with a pressure vessel. Circulation heaters are designed to heat forced-circulation air, gases or liquids. It maximizes dielectric strength, heat transfer and life. It also reduces the heat loss from the vessel.

Clamp back spacers are used to securely mount conduit to a wall or other structure for support. It is a flat base member having opposite upper and lower surfaces. It is used with malleable or stamped pipe straps to provide a mounting stand-off for a conduit from a wall or other structure.

Clamp-on testers is one of the most basic testing tools, which provide nonintrusive method for measuring electrical current. They feature AC/DC current measurements with current ranges up to 300A, mean value display and sleep function.

A clamp meter (clamp-on ammeter) is a type of ammeter, which measures electrical current without the need to disconnect the wiring through which the current is flowing. Clamp meters are also known as tong testers or Amprobes, one of the first vendors of such devices. The most common forms of clamp meter are, a probe for use with a multimeter, a self-contained unit, a built-in part of a specialized multimeter used by electricians. In order to use a clamp meter, the probe or clamp is opened to allow insertion of the wiring, and then closed to allow the measurement. Only one conductor is normally passed through the probe, if more than one conductor were to be passed through then the measurement would be a vector sum of the currents flowing in the conductors and could be very misleading depending on the phase relationship of the currents.

Clonable Transponder Key Kit is the starter kit for repli-code 7 or repli-code 7 TX owners. Kit includes a sturdy case and application chart for fixed head clonable keys.

CO Type Portable Power Cables are single or multiconductor and supplied with or without shielding. The cable resist temperature extremes and remain flexible from as low as -55degree celsius to +90 degree celsius. They feature highly tailorable construction and excellent termination molding compatability.
