Phoenix Contact's PLH 5 and PLA 5 PCB terminal blocks have a lever for connection and release of the conductor without the use of tools. The soft-touch lever comes in the open position, ready to accept the wire. Light finger pressure is all it takes to complete the connection. The spring cage creates a gas-tight wire termination, which self-adjusts with temperature changes and vibration conditions. The housing size is compact compared to other terminal blocks with similar current and voltage ratings.
