Panel fit and mounting constraints
The 3RT2526-1AH20: The side clearance requirement is 6 mm; zero clearance is allowed upward, downward, forward, and backward, so you can pack multiple units tightly in a row as long as the 6 mm side gap is maintained.
Switching capacity and coil specs
These are the rated operational currents for DC-1 through DC-13 loads — the voltage step-down is steep above 125 V, so confirm the load voltage against the table before specifying. AC operating time is 4 to 16 ms; arcing time is 10 ms. Maximum switching frequency is 1,000 cycles/hour in AC-1 duty and 1,500 cycles/hour for DC operation. Power consumption at the coil is 0.25 VA at 50 Hz and 0.28 VA at 60 Hz. An auxiliary switch is included as standard.
