Built to the highest quality standards SecoBloc is designed and fully tested to 2014 IEC standards. It utilizes GE’s latest SecoVac vacuum circuit breaker, third-party tested in accordance with IEC 62271-100. Manufactured in accordance with high quality standards, GE engineers have integrated core technologies. Circuit breaker and mechanism design, vacuum arc control technology, insulation technology and electrical field control and analysis combine to create a highly reliable and compact system. SecoBloc reflects GE’s best MV switchgear design practices.

Construction type and IP rating SecoBloc Type BC/BV is designed and constructed to meet the requirements IEC 62271-200 for Indoor installations. SecoBloc offers IP43 protection from penetration of solid objects and liquids on the front side with its door closed.

Earthing SwitchThe SecoBloc earthing switch can be closed under short-circuit up to 40kA. The earthing switch isolators are provided with a capacitive voltage sensor for connection with the voltage presence indication system.

SecoVac MechanismThe SecoVac circuit breaker utilizes a compact, spring charged operating mechanism. The open and close mecha-nisms are combined into a single, small and easily replaceable module.

Automatic ShuttersThe SecoBloc OEM blocs are equipped with grounded metal shutters in front of the primary bushings. The shutters are automatically operated by the circuit breaker movement. When the circuit breaker is racked out to the test or disconnect positions, the shutters automatically close to isolate the fixed primary contacts. As an option, shutters are available with a safety interlock, which in the absence of a withdrawable apparatus, will prevent manual activation.

Marine ApplicationSecoBloc has been tested for Marine applications according to the IEC 60068-2-6 and IEC 60092-504.

Inclination Test– Determines that SecoBloc can continue operating as intended, even when inclined at an angle up to 25 degrees on all four sides.

Vibration Test - The operating conditions on marine platforms and shipping installations require the capability to work in environments

affected by vibrations. SecoBloc was exposed to a resonance search and endurance random, which consists of a random vibration test according to IACS E10.

Vibration Sweep Test:• From 2 to 13.2 Hz displacement

1.0 (peak value)

• From 13.2 to 100 Hz acceleration amplitude of 0.7 g

• Vibration Endurance Test - 90 minutes

The exposure to these severe service conditions confirms the suitability of SecoBloc to unstable marine conditions. The SecoBloc Marine version includes a handrail in the breaker compartment door as well as doorstoppers.

Voltage Transformer TruckThe withdrawable trucks also allow fuse replacement with the switchboard in service. Truck racking out with the door closed automatically operates closure of a metallic segregation shutter between the live parts of the switchgear and the instrument compartment.

Disconnect TruckDisconnect truck is used to disconnect primary circuit and normally coupling with bus bar tie breaker to achieve two section power supply. Disconnect truck can be provided with bus tie/ riser panels.

Earthing SwitchThe earthing switch can be operated from the front of the module. It is mechanically interlocked with the circuit breaker truck so that the earthing switch can only be operated when the circuit breaker is open in the test/disconnect position. The switch is also mechanically interlocked with the cable compartment door for additional safety.
