B59 series overcurrent protection magnetic ring discs are used for line card applications. The magnetic ring discs have the following features: comply with ITU-T K20, K21, K45 standards basic level lightning surges (10/700 µs), basic level power induction (600 V, 1 A, 0.2 s) and power contact standard A/B (230 V, 15 minutes); suitable for continuous connection to mains voltages of 110/230 VAC in tripped (high ohmic) condition; narrow resistance tolerance.
This leaflet presents the application data, electrical specifications and dimensional drawings for EPCOS leaded‑disk line‑card components. It includes over‑current protection details, compliance with ITU‑T standards and delivery options such as cardboard tape or AMMO packs.
General technical data cover rated voltage, resistance tolerance, operating temperature range and maximum switching voltage for both kinked and straight leads. Characteristic curves for PTC resistance versus temperature are also provided. This manual is written in German.
| Rated voltage | 230 V |
|---|---|
| Maximum switching voltage (kinked leads) | 265 VAC |
| Maximum switching voltage (coated type) | 600 VAC |
| Dimensions B 1610 (kinked) | bmax 10.2 mm, hmax 13.1 mm, smax 5.0 mm |
| Dimensions B 1008 (straight) | bmax 8.2 mm, hmax 8.2 mm, smax 4.0 mm |
The maximum switching voltage for kinked leads is 265 VAC.
The B 1610 kinked lead measures 10.2 mm (bmax) × 13.1 mm (hmax) × 5.0 mm (smax).
It complies with ITU‑T K20, K21 and K45 at basic level lightning surges and power induction.
