The BTBH-H Series Surface Mount Terminal Blocks offer an easy-to-assemble, finger-safe (IP20) solution for electrical connections. Featuring a touchdown screw structure for quick wiring and flexible assembly without connecting rods, these terminal blocks reduce wiring time and the number of parts required. They are suitable for space-saving installations and are environmentally friendly due to reduced part count and ease of disassembly. Mixed terminal block combinations are possible using joint plates, allowing for unlimited pole assembly and flexibility for specification changes or maintenance.
