Frequently Asked Questions (FAQ)
Q1: What is the difference between MS116 (thermal-magnetic trip) and MO series (magnetic-only trip)?
The MS116 uses thermal-magnetic trip technology, which provides both overload protection (thermal) and short-circuit protection (magnetic). The MO series provides magnetic-only trip, which is suitable for applications where overload protection is handled by a separate device, such as a soft starter or variable frequency drive.
Q2: What is the rated current range of the MS116 motor protection circuit breaker?
The MS116 has a rated operating current range of 0.16 A to 32 A, with a current setting range of 0.1 A to 32 A. This makes it suitable for protecting motors from 0.03 kW up to 15 kW at 400/415V.
Q3: Does the MS116 provide phase failure protection?
Yes, the MS116 includes built-in phase failure protection. This feature detects loss of one phase in a three-phase system and trips the breaker to prevent motor damage from running in a single-phase condition.
Q4: What is the short-circuit breaking capacity (Icu) of the MS116 at 400/415V?
The short-circuit breaking capacity varies by model. For example, MS116-0.16 to MS116-10 offer up to 50 kA, MS116-12 offers 25 kA, MS116-16 offers 16 kA, and MS116-20 and MS116-25 offer 15 kA (Icu). The MS116-32 has a breaking capacity of 10 kA.
Q5: What is the ambient operating temperature range for the MS116?
The MS116 is designed to operate in ambient air temperatures ranging from -25°C to +55°C (compensated). Compared to the MS132 and MS165 which can operate up to +60°C, the MS116 is slightly more limited but still covers most standard industrial environments.
Q6: How does the MS116 compare to the MS132 and MS165 in terms of features?
All three models offer thermal and magnetic protection, phase failure protection, and isolation function. However, the MS132 and MS165 additionally provide ON/OFF/TRIP switch positions, magnetic trip indication, and a lockable handle without accessories — features not available on the MS116. The MS165 also has a wider body (55mm vs 45mm) and supports higher currents up to 65A.
