  • Large contact surface results in higher wire retention force
  • Functional reliability after repeated tightening and loosening

Curtis Industries has years of experience producing the highest quality DIN terminal/rail blocks for custom and standard applications for industries across the globe. Terminal blocks are designed for use in industries which require high-current input and output connections. Our terminal and rail blocks are long lasting and reliable. Throughout the entire manufacturing process, our engineers perform frequent quality control tests – ensuring even the slightest defects are immediately corrected. All our electrical products are UL and CSA certified.

Curtis has industry leading capabilities, our products consistently go above and beyond customer expectations. Our DIN terminal blocks easily mount on standard DIN rails and feature a vibration resistant clamp design. Our components remain functional even after repeated tightening and loosening, while the large contact surface results in a higher wire retention force. Invest in quality, rely on Curtis Industries for all your electrical components.

Screw Connections

DIN rail blocks with screw connections keep wires in place by the tightening and loosening of a screw. Curtis Industries can manufacture custom or standard screw connection rail blocks. These types of blocks are used extensively in wiring buildings – such as connecting electrical outlets and switches to the mains. They’re available in single level, dual level and triple level options. All our DIN rail terminal blocks with screw connections feature polyamide 66.6 VO plastic body, a silver-plated copper internal bus and nickel-plated brass clamps. The screws are yellow-chromated steel.

Screwless Connections

Screwless connection rail blocks offer a convenient alternative to the popular screw clamp connectors. Curtis Industries screwless terminal blocks feature a spring, which can be easily opened using a tool, such as a screwdriver, so a wire can be fed in through the opening. When the spring is released, it forms a secure connection with the wire. These types of blocks are used across a wide variety of industries due to the fast installation and increased safety features. We manufacture screwless terminal blocks in single level, single level with multiple wire connections, triple level and ground block options. Our screwless connection terminal blocks are manufactured with a polyamide 66.6 VO plastic body featuring stainless steel springs and a tin-plated copper internal bus.

Screwless Connection Ground Blocks

Ground terminal blocks are used to connect wires to the DIN rail by using a conducting clamping foot. This way, the DIN rail can act as a ground bus bar. Much like the screwless connectors, screwless ground blocks are maintenance free and provide secure connections. They also feature the 66.6 polyamide VO plastic body with tin plated copper internal bus. The brass clamping foot is tin-plated and the spring is stainless steel

Fuse Blocks

A fuse block is a critical component in keeping you electronic equipment from surges and overheating. Fuse blocks from Curtis Industries provide a convenient way of protecting sensors and relays. We manufacture various series of fuse boxes, making adding fuses to your DIN rail wire panel easier. We offer the following series of DIN rail fuse blocks:

  • 6102050
  • 6104110
  • 6104500
  • 6104600
  • 6110110

Manufactured to the highest standards, our fuse blocks feature a Polyamide 6.6 VO plastic body and hardened steel zinc yellow chromated electro-pleated clamps. In addition, they are steel zinc plated and have 4 marking slots on both sides.

Mounting Rails and Accessories
