SDH TYPE DISCONNECTING TERMINAL BLOCK
FEATURES
Enabling high voltage of 1,000V DC/13 A※1to be cut off.
The original mechanism (with the built-in magnet andarc-extinguishing grid) enables high-voltage to be cut off.*1 Type of load applied: DC-21B
Lever operation system is used.
Through lever operation,
smooth and accurate
ON/OFF switching is
enabled.
Easy-to see ON/OFF
indicator is provided.
Finger protection
Finger protection structure on terminal-portion prevents touching live portion even if terminal cover is not attached.
Rated insulation voltage is 1,500V DC / 1,000V AC
1,500V DC/ 1,000V AC insulation performance is
provided.
* Conforming to IEC60947-3
Quick and easy DIN-rail mounting and removal are enabled by unit.
By operating the stopper, you can remove each unit easily without detaching the fastening bracket.
Erroneous operation prevention cover to ensure safety.
