Technical Specifications
Switching frequency
• With resistive load
2 Hz, maximum
• With inductive load in accordance with IEC
60947-5-1, DC13
0.1 Hz, maximum
• With inductive load in accordance with IEC
60947-5-1, AC15
2 Hz, maximum
• Inductive load in accordance with UL 508
Pilot Duty B300, R300
Voltage induced on current interruption
(internally) limited
No
Short-circuit protection of output No, external fusible cut-out, 6 A, operating class
gL/gG; with two outputs wired in parallel, each
output must be fused with a 6 A fusible cut-out,
operating class gL/gG. Note that for applications
in accordance with EN 50156-1, the specified
rated current of the overcurrent protective device
must be multiplied by the safety factor 0.6 to rule
out the error "non-opening of contact elements
due to permanent contact welding".
Time, Frequency
Switching time Typically 13 ms
Release time Typically 16 ms
Protection against Overvoltage
Protection of outputs from surge in accordance
with IEC 61000-4-5 (no protection elements
required)
