Connectorized® Products
Connectorized products offer the advantage of robust connections while minimizing installation and replacement time. Now, installing or removing an SEL device with Connectorized terminals only takes a few minutes. All wiring remains connected to the terminal blocks. Each terminal block mates with a connector in the SEL device. Each connector features positive-retention screws to prevent accidental disconnection due to the weight of wire bundles, vibration, or physical shock.
We provide the following styles of proven, high-reliability terminal blocks.
- Connectorized Terminals: Crimp wires into connectors that fit in the terminal block; the terminal block is rated for ac current and ac voltage inputs. For current inputs, the block includes automatic shorting of the CT leads.
- Compression Screw Terminals: Insert wires into the terminal block, and tighten screws to secure the wires.
- Screw-Terminal Connectorized® (STC): Screw terminals on the plug accept standard ring terminals (Patent D0492,653).
Each of these connectors has been thoroughly tested by its manufacturer and proven over time in many industry applications. In addition, SEL tested these connectors to verify conformance to our standards for protective relay applications.
