Connectwell industries introduces screwless spring clamp terminal blocks. These terminal blocks are ideal for 10-sq mm wire. The wire in the spring clamp terminals is held against current bar directly by pre-stressed spring clamp. The operation of the spring clamp is done by using a screwdriver to provide an access to wire through the opening in the spring clamp. The wire end gets clamped on to the current bar on removal of screwdriver. The terminal blocks employ top wire entry system. The terminal blocks are suitable for mounting on din 3 rail [din 35]. Insulated push-in type cross connecting links besides providing shock protection, simplify the task of cross connection.
