1) Consult TE Connectivity for insulation compatibility with higher voltages.
2) Load circuit: L <100µH.
3) After 10 fault break operations relay must be replaced.

5) Valid for recommended 250Ω suppression resistor (PCB version).
Note: A low resistive suppression device in parallel to the relay coil increases the release
time and reduces the lifetime due to increased erosion and / or higher risk of contact tack
welding.

Notes regarding processing of PCB version:
• Coating of relay is not permitted. If coating of PCB is necessary, the area of relay on top
and bottom side must be left out.
• Only wave soldering (max. 260°C with thermal screen/10s) is permitted; no reflow or
hand soldering.
• Other process temperatures (e.g. drying of PCB after coating) must not exceed 85°.

Notes regarding PCB-layout:
•
Terminal 4 is at HV potential only when the relay is closed.
This terminal must not be connected electrically.
•
Terminals 8a and 8b are at no electrical potential, but
connected internally.
Minimum distance to neighboring ferruginous parts: 3mm.
Recommended relay socket:
•
TE part number 1-1904045-2
Suitable crimp terminals:
•
TE part number 5-160526-9 (coil)
•
TE part number 0-160927-4 (contact)
The required clearance and creepage
distances between parts connected
to HV potential (terminals 4, 5, 7)
and parts connected to LV potential
(terminals 1,2) must be ensured.
