A Complete Guide to Isolators and Switch Disconnectors
2023年1月30日 · Standard models are single phase while a three-phase isolator is often preferred for very high voltage equipment. These combine three isolator switches in one, providing a higher level of safety for the electrician or engineer about to carry out maintenance work.
Isolators: What Are They? (Working, Definition and Uses)
2021年3月16日 · An isolator is a type of mechanical switch that is used to electrically isolate electrical circuits from current passing through them. Isolators are used to locally power on and power off machinery when needed for operation, fault finding, or maintenance work.
These isolation switches are most commonly used to isolate the power stage from the battery voltage, or isolate individual motor phases to allow for fail-operational functionality. Figure 1. High-Side and Phase Isolation Switches.
3 Phase Disconnect Switches for Reliable Power Distribution
Isolator switches are 3 phase disconnect switches without fuses. They utilize quick break mechanisms and visible blades. Features: Heavy duty handles with multiple lockout options; Visible contact position from the side; High SCCR for available faults up to 200kA; Ratings from 400A to 3000A; Benefits: Reliably isolate equipment with no protection
