TB-438 Timer

Buyer Overview

KANGGE ELECTRIC supplies the TB-438 series for importers, distributors, panel builders, machinery manufacturers, contractors and OEM electrical-equipment buyers.

The TB-438 24 hour timer provides scheduled switching for lighting and other daily-operated electrical loads. A 15-minute setting interval supports recurring schedules, and a working reserve maintains timekeeping during temporary supply interruptions.

TB-438 Quick Selection: Confirm the exact model, supply or coil voltage, timing or current setting, contact arrangement, mounting method, application and quantity before quotation.

Product Advantages

• •The daily timer with 150 hour reserve maintains timekeeping during a temporary supply interruption; the reserve does not power the connected load.
• •The 96 interval scheduling timer divides a 24-hour cycle into repeatable settings.
• •A 15 minute daily switching cycle setting unit supports recurring equipment schedules.
• •The TB-438 10A time switch has an AC220V contact rating; select the device for the actual load.
