Non-Fused Switch Disconnectors

Non-fused switch disconnectors are safety devices that use a knife-blade or rotary disconnect to shut down a circuit for maintenance and servicing. They protect the circuit by cutting the power supply to the isolated parts of the circuit. A fused switch disconnector exploits a fuse to break the circuit, while versions of non-fused instead use a rotary switch or knife-blade disconnect. As a result, these switch disconnectors are easy to reset without replacement fuses. A rotary switch disconnect typically works by breaking the circuit by rotating a lever, and a knife blade disconnect lifts a lever off a specific slot inside the device using a hinge.

Types of Non-Fused Switch Disconnectors

These non-fused disconnectors come in various settings to meet the requirements, including the type, maximum current, voltage rating, geographical region, terminal, and mounting types. Each one is segmented on above mention type given below:

  • By type - the market for global non-fused disconnectors can be segmented into rotary or knife-blade. 
  • Based on voltage - the switch disconnector market is divided into high, medium, and low voltage. 
  • Electric phase-type - these global non-fused disconnectors market is divided into single-phase and three-phase. 
  • By geographical regions - the global market for these disconnectors is split up into Europe, North and South America, the Middle East and Africa, and the Asia Pacific.
  • By application - the non-fused disconnectors market is segmented into residential and commercials.

Typical Applications of Switch Disconnectors

These non-fused disconnectors have crucial applications in various settings, including:

  • They are mainly used as safety or isolator switches and are electrical safety devices.
  • They manually disconnect power from circuit breakers and transformers by turning the handle precisely. 
  • They are commonly used in control settings and industrial automation.

Switch Disconnectors for Photovoltaic Systems The ABB OTDC series switch-disconnectors are expertly designed for PV applications and are most commonly used to isolate single strings or arrays of solar panels and battery banks. The switch disconnectors can also act as the main switch for the entire photovoltaic application. Compact size Unique safety features Simple and quick installation Safe and reliable OTDC 16…32 Amperes OTDC from 16…32 Amperes have numerous DC ratings within the same footprint space and the rated operational voltage can be scaled up to 1000 V to suit your application. Tunnel terminals capture fine stranded wires and they are wide enough to allow wires up to 16 mm and short circuit bars are preinstalled as standard. OTDC 100...250 OTDC switches from 100…250 Amperes are the only 2-pole solution in the market with an operational voltage of 1000 VDC. This is possible thanks to carefully optimized arc plates and dual magnetic breaking.The switches are symmetrical in design and connections are independent of polarity, meaning they can work in both ways. The OT range of switch disconnectors are suitable for use in a variety of applications including motor control centres, switchboards and as main switches in machines.
