TBC TCT-463 Modular Contactor 4-Pole 63A 400V AC

Electrical Performance:

The TCT-463 is rated for continuous operation at 63A with a maximum operational voltage of 400V AC. The rated insulation voltage of 500V AC provides adequate safety margin for standard low-voltage installations. The AC-7a utilization category makes it particularly suitable for resistive and slightly inductive loads including lighting circuits, heating elements, and auxiliary equipment.

Control Circuit:

The electromagnetic coil operates on 230V AC at 50/60 Hz, compatible with most standard control circuits. The A1-A2 terminals accept control signals from switches, timers, building automation systems, or other control devices. The coil design ensures reliable operation across the specified frequency range.

Contact Configuration:

Four normally open (NO) poles provide independent switching for three-phase plus neutral, or multiple independent circuits. Each pole is rated for the full 63A capacity. Contact terminals are designed for secure connection of conductors and feature clear numbering for easy identification.

Mechanical Design:

The compact modular design occupies 4 standard DIN-rail modules (72mm width), allowing efficient use of panel space. The snap-on mounting mechanism ensures quick installation and removal from standard 35mm DIN rails. The flame-retardant thermoplastic housing meets modern fire safety requirements and provides IP20 ingress protection suitable for enclosed distribution boards.

Standards Compliance:

Manufactured in accordance with IEC/EN 61095 standards for contactors and motor-starters. CE marking confirms conformity with applicable European directives for safety and electromagnetic compatibility.
