CTB93HE/3

The CTB93HE/3 is a 3-way pluggable PCB terminal block designed for secure and efficient wire-to-board connections in control, signal, and low-voltage power applications. With a compact 3.81 mm pitch and a rising-clamp termination system, it supports wire sizes from 0.2 mm² to 1.0 mm² (30–16 AWG), ensuring reliable retention for both solid and stranded conductors. Rated for 10 A at 200 V (UL rating 8 A at 300 V), it delivers dependable electrical performance with a dielectric strength of 2.5 kV and impulse withstand capability up to 2.5 kV. The housing is manufactured from flame-retardant PA66 nylon with a UL94-V0 rating, offering durability and safety in demanding environments. Copper alloy contacts with tin over nickel plating and captive zinc-plated steel screws provide long-term reliability, while the pluggable design simplifies assembly and maintenance. Fully compliant with UL, VDE, and RoHS standards, the CTB93HE/3 is ideal for industrial and commercial electronic assemblies requiring compact, approved connectivity with convenient plug-in functionality.
