Width is 45 mm, depth 50 mm, height 26 mm, so it occupies a single modular slot. Wire termination accepts 2x (20 … 14) AWG solid or stranded. That covers most control-circuit wiring in a standard panel — no need for ferrule adapters unless your shop standard calls for them.

Frequently asked questions
Where can I buy the 3RT1926-2DG21 and get a price?
This timing relay is sourced and quoted to order against an RFQ through independent distribution. Submit a request for a firm price and availability — confirmed at quote time.
What is the adjustable time range on this relay?
The 3RT1926-2DG21 adjusts from 0.5 to 10 seconds. That range covers most OFF-delay needs for post-run cooling, sequenced vent dampers, or delayed-dropout control circuits.
What supply voltage does this timing relay need?
It accepts 24 to 66 V AC (50/60 Hz) and DC — universal across that band, so one relay covers both AC and DC control circuits in that voltage window.
What is the recovery time between cycles?
Recovery time is 150 ms, and the minimum ON period is 35 ms. That means it can re-trigger quickly in cycling applications without missing a timing cycle.
