HP3A/H enclosures use screw locking and a compact shaped interface. The range includes surface bases, a bulkhead base, a right-angle bulkhead housing and a top-entry M20 hood. Select the mounting format, mating interface and cable route before assembly.

| Model | Configuration | Entry or passage | Drawing designation |
|---|---|---|---|
| HP3A/H-SF-2H | Surface-style housing with bottom panel passage | Bottom passage and side-facing mating interface | HP3A/H-SF-2H |
| HP3A/H-SG-2H-M20 | Surface base | One M20 side entry | HP3A/H-SF-2H-M20 |
| HP3A/H-BK-SE | Right-angle bulkhead housing | Bottom passage and side-facing interface | HP3A/H-BK-SE |
| HP3A/H-BK-2H | Bulkhead base | Bottom panel passage | HP3A/H-ST-2H |

The SF-2H and M20 surface-base configurations are 41.50mm high, with a 51mm-square mounting flange and 52mm overall depth. Their four M4 panel fixing positions are spaced 41×41mm. The flange slots are 4.40mm wide. The bottom-passage SF-2H requires a 40mm-diameter panel opening; the M20 side-entry version uses the four fixing positions without that cable-passage cutout.
| Configuration | Dimensions | Mounting detail |
|---|---|---|
| HP3A/H-BK-2H | 45.40×32.20mm outline; 20.30mm body height with 4mm raised interface | 22×22mm panel opening with R2.50 corners; two 4.20mm holes on 30mm centres |
| HP3A/H-BK-SE | 45.40mm across the mounting flange; 27.50mm flange depth | 22×22mm panel opening with R2.50 corners; two 4.20mm holes on 30mm centres |
| HP3A/H-TE-2S-M20 | 45.40×32.20mm flange; 54.90mm body height | Two screw locking positions; M20 cable entry |
Use the individual drawing to check the mating screw positions and mounting clearance. Fit the selected insert and the cable gland required for the M20 entry and cable diameter. Seat all seals correctly and engage both locking screws evenly. The installed insert determines contact count and electrical ratings.
