FOR THREE-PHASE POWER SUPPLY
Functions & Features
Y: Without
• Connected in parallel between the power and earth lines
regardless of load current
• Applicable to single phase 2/3-wire and threephase 3/4-
wire system
GENERAL SPECIFICATIONS
Construction: Standalone; terminal access at the front
Degree of protection: IP20 (If the solderless terminals are
covered with insulation tubes.)
• High discharge current capacity 20 kA or 40 kA (8/20 μs)
• Degraded head element is automatically separated from
the power lines by the incorporated thermal breaker, and
the LED lamp (turns off) and the relay contact alerts the
failure status.
Surge protection type: Voltage limiting type one-port SPD
Connection
Line: M5 screw terminal (torque: 2.5 N·m)
Alarm output: Tension clamp
• Complies with IEC 61643-1 Class II
Applicable wire size
Typical Applications
Line: See the drawing below.
• Low-voltage distribution board
• Combination with installation for large load current
Alarm output: 0.13 to 1.5 mm
2, stripped length 8 mm
Screw terminal
Line: Nickel-plated steel
50 [1.97]
Alarm output: Tin-plated copper alloy
Housing material: Flame-resistant resin (black)
Alarm output: SPDT relay contact trips when the thermal
breaker operates.
