Features :

• Sensing by electronic circuit
• Low supervision current
• Immune to breaker operation
• Continuous monitoring

The indicator consists of an armature which rotates between the poles of an electro magnet. The indicator pointer which is black in colour, is fixed to the armature and turns against a white background. When the circuit breaker or isolator is in closed position, the pointer bridges the gap between the lines and provide continuity in the mimic diagram. When the circuit breaker or isolator is in open position, it takes up a position which is at right angles to the mimic. If the supply to the indicator fails, then it takes up an intermediate position i.e. at 45.

The indicator is housed in a cylindrical moulded case and is designed essentially for flush mounting on control panels. A mounting clamp is provided on the case for fixing on to the panel.

Semaphore indicator is available in two versions viz. JAV 041 is used for circuit breakers and a beezel diameter of 63mm, type JAV 042 is used for isolators& earth switches and has a beezel diameter of 48mm. However, the panel cut out dimension is 41mm dia, which is the same for both the types. The indicator coil is basically designed for 24/30V DC rating. For 48V, 110V & 220V DC application, a screw type series resistor is supplied which can be directly screwed on to a terminal of the semaphore.

The 'CGI 14S' Self Powered Numerical ProtectionRelay is designed for use in unmanned substation where dependable auxiliary power source is not available. Therelay derives power for its operation from main current transformers. It also comprises integrated communication protocols for SCADA compliance.

A Remote/Local control selector switch can often be situated in proximity to the controlled plant [i.e. LOCAL to the equipment] and allow an operator to take control locally and avoid the need to interact or accept remote supervisory commands.

3M Heat Shrink MV Termination Kit offers reliability and flexibility to meet the demands of cable network operators. The terminations are available for 11, 22 & 33 kV. The components of the kit are designed for conditions where the terminations are exposed to rainfall, outdoor sunlight, extremes of weather and heavily polluted areas. The specially engineered kits also take care of the typical partial and surface corona discharge for all power cables under challenging service conditions.

Rotary Selector Switches are suitable for instruments like Ammeters, Voltmeters, Power Factor Meters etc. The design enables to indicate by means of a single meter, the current or the voltage. Ammeter Selector Switches are provided with make - before - break contacts to give security against risk of open circuit of the current transformer secondaries. Listed below are standard switches.

TNC Switch - TNC or CAM SwitchThey are used as Control switches in Control Panels and equipments such as Phase Changeover Panels, MV & HV - Vacuum Circuit Breakers, Gas Circuit Breakers, On Load Tap Changers, Motor control panels, instrumentation Panels, Machine tools & Electro-medical equipments. The switches are used as Mains switch, Selector Switch, Programme Switch or for tripping or closing of breakers either locally or from remote site. These switches offer advantage of having unlimited combinations of switching angels and indexing angels with stay put and spring return momentary contacts. Lost motion contacts can be cascaded, used for additional protection or for activating annunciator.

Tripping coil is a part of an automatic circuit breaker. It is connected to a sensitive circuit that is designed to disconnect power line. It is triggered by excessive current flow through the breaker. When it energizes, it causes the breaker to open and interrupt the flow of current.
