You are viewing the ETI CH14 Cylindrical Fuse Link 14x51mm 20A 690V gG Class 3-Pack, which is being compared against several similar cylindrical fuse links from the ETI and Eti-Polam brands. All presented items share the same 14x51mm physical dimensions and gG operational class, but differ in rated current, voltage ratings, and package quantities.
⚙️ The specifications, dimensions, electrical parameters, and package contents are compared below to help you determine the most suitable option for your electrical installation.
| Parameter | ETI CH14 20A 690V (3-Pack) | ETI CH14 25A 690V (3-Pack) | ETI CH14 32A 500V (3-Pack) | ETI CH14 40A 500V (3-Pack) | Eti-Polam 16A 690V (1-Pack) | Eti-Polam 12A 690V (10-Pack) | Practical Conclusion |
|---|
| Size | 14x51mm | 14x51mm | 14x51mm | 14x51mm | 14x51mm | 14x51mm | All models are fully physically interchangeable and fit standard CH14 fuse holders. |
| Rated Current | 20A | 25A | 32A | 40A | 16A | 12A | The choice depends on the calculated load current of the protected circuit; each model is designed for a specific tripping threshold. |
| Voltage Rating | 690V | 690V | 500V | 500V | 690V | 690V | The 20A, 25A, 16A, and 12A models support up to 690V, whereas the 32A and 40A versions are rated for 500V. |
| Operational Class | gG | gG | gG | gG | gG | gG | All links provide standard general-purpose industrial protection against overloads and short circuits. |
| Package Quantity | 3 pcs | 3 pcs | 3 pcs | 3 pcs | 1 pc | 10 pcs | Supplied quantities range from single units to packs of 3 or 10 pieces to match different installation scales. |
◎ The table below evaluates different use cases and user needs to help you select the most appropriate fuse modification.
| Use Case | Recommended Product | Why |
|---|
| Protection of distribution circuits with loads up to 20A at voltages up to 690V | ETI CH14 Cylindrical Fuse Link 14x51mm 20A 690V gG Class 3-Pack | Provides the exact 20A rating required for the circuit while supporting higher voltages up to 690V in a convenient three-pack. |
| Protection of lines requiring higher current ratings (25A, 32A, or 40A) | Alternative models rated for 25A, 32A, or 40A | Required when safeguarding power lines with heavier operating current demands, noting that the 32A and 40A versions operate at 500V. |
| Installation in smaller circuits requiring 12A or 16A protection | Eti-Polam models rated for 12A or 16A | Suitable for equipment with lower current thresholds, with the 12A option conveniently supplied in a larger 10-piece pack. |
The primary difference of the ETI CH14 Cylindrical Fuse Link 14x51mm 20A 690V gG Class 3-Pack compared to the alternatives is the combination of a 20A rating, 690V voltage support, and a three-piece pack. This option is ideal for electrical installations requiring precise 20-amp protection under elevated voltage conditions. Choose this product if your design specifications match the 20A rating and you require a pack of three elements.
