Product Overview
Four reviewed photographs show the same S3-B1370 structure from distinct views: complete roller-and-lever assembly, readable side label, covered contact terminals and opposite side profile. The original markings are retained for electrical and model verification.

Specification Confirmation
| Item | Reviewed reference | Order check |
|---|
| Model | S3-B1370 | Confirm the complete physical label and wide-body version |
| Product type | Roller-actuated elevator limit switch | Confirm the intended limit or safety-circuit position |
| Standard marking | GB 14048.5 | Confirm project and local acceptance requirements |
| AC utilization rating shown | AC-15: 220 V / 2 A | Confirm the actual load category and circuit duty |
| DC utilization rating shown | DC-13: 110 V / 0.3 A | Confirm voltage, load and switching frequency |
| Insulation reference conflict | Physical label: Ui/Ith 500 V; backend record: insulation voltage 380 V | Obtain the supplied revision datasheet before final selection |
| Backend environmental reference | −5 to +40 °C; IP20 | Confirm against the actual unit and installation environment |
| Backend breaking-capacity reference | 1000 A | Do not apply until confirmed by exact-model documentation |
| Mechanical interface | Large roller, lever linkage, return spring and covered screw terminals | Compare wheel diameter, lever travel, mounting and terminal access |
The 500 V marking on the photographed unit does not match the 380 V backend entry. This conflict is intentionally retained for confirmation rather than resolved by assumption.
Buyer Confirmation Checklist
Electrical match
Confirm AC-15 or DC-13 duty, operating voltage, current, contact state, terminal layout and safety-controller requirements.
Mechanical action
Check roller diameter, lever direction and travel, spring return, operating force and available clearance.
Mounting and environment
Compare body width, mounting holes, terminal-cover access, ambient temperature and required ingress protection.
Frequently Asked Questions
Can another S3-B1370 listing be used without checking dimensions?
No. Confirm the wide-body housing, roller and lever geometry, mounting points, contacts and full label.
Which insulation-voltage value should be used?
The supplied photograph shows 500 V while the backend record says 380 V. Obtain an exact-revision datasheet or supplier confirmation before selection.
What is required for replacement review?
Provide the old unit's full label, installed position, contact state, circuit duty, body and mounting dimensions, and roller travel.
Selection note: Final compatibility depends on the exact housing, actuator geometry, contacts and electrical duty. Resolve the 500 V versus 380 V record conflict before ordering.
