CTS Screw clamp Terminal Blocks
Connectwell
CTS Series Terminal Blocks, also known as screw clamp terminal blocks, DIN rail
terminals, feed-through terminals, or panel wiring connectors, are engineered
for secure and high-performance electrical terminations. In this technology, a
screw tightens the clamp to press the conductor firmly against the
current-carrying element, creating a strong and reliable connection. The
applied torque ensures consistent contact pressure, reducing resistance and
enhancing conductivity compared to conventional low-grade terminals. Ideal for
high-current circuits, these terminal blocks are widely used in control panels,
switchgear assemblies, PLC panels, OEM machinery, and industrial automation
systems.
Sizes (Cross-Section Range): 0.5 mm² to 25 mm² (model dependent)
Mounting: Standard DIN Rail
Mounting
Housing: Flame-retardant
Polyamide (PA 6.6), UL94 V-0
Protection Class: IP20
(Finger-safe design as per IEC standards)
CP Push - IN Terminal Blocks
Connectwell Push-In Series Terminal Blocks, also known as push-fit terminal blocks, spring clamp terminal blocks,
pluggable DIN rail terminals, or tool-less wiring terminals, are designed for
fast, secure, and vibration-resistant electrical connections. Featuring
advanced spring clamp technology, they enable direct conductor insertion
without screws, reducing installation time and ensuring consistent contact
pressure compared to conventional screw-type terminals. Their compact modular
design optimizes panel space while enhancing wiring reliability. Widely used in
control panels, PLC systems, switchgear assemblies, OEM machinery, and
industrial automation cabinets, these terminal blocks deliver safe, efficient,
and maintenance-friendly connectivity in demanding industrial environments.
Sizes (Cross-Section Range): 0.2 mm² to 16 mm² (model dependent)
Mounting: Standard DIN Rail
Mounting
Housing: Flame-retardant polyamide (PA 6.6), UL94 V-0
Protection Class: IP20 (finger-safe design as per IEC standards)
CX Spring Clamp Terminal Block
Connectwell CX Series Terminal Blocks, also known as spring clamp terminal blocks, tension clamp terminals,
DIN rail spring terminals, or vibration-resistant panel connectors, are
engineered for secure and maintenance-free electrical connections. Featuring
high-tensile spring clamp technology, the mechanism applies constant contact
pressure on the conductor, ensuring stable connectivity even under high
vibration and thermal cycling conditions. Unlike conventional screw-type
terminals, no re-tightening is required over time. Designed to accommodate both
solid and stranded wires, these terminals are ideal for control panels,
automation systems, railway applications, OEM machinery, and industrial
environments demanding long-term reliability.
Sizes (Cross-Section Range): 0.2 mm² to 16 mm² (model dependent)
